Product Resources

99.9% Filtration Efficiency. Royal Purple Extended Life Oil Filters use a 100% synthetic micro-glass screen-backed media for superior particle removal with a 99.9% filtration efficiency at 25 microns all while not sacrificing flow.

Anti-drain Back Valve. Royal Purple filters feature a unique silicone anti-drain back valve that prevents dry starts by eliminating oil drain back during shutdown. Silicone outlasts and outperforms standard nitrile rubber in both extreme hot and cold oil.

Superior Construction. Royal Purple Filter housings have a much thicker shell wall for additional strength to provide security against a puncture from road debris. Along with a heavy duty rubber base gasket and steel back-plate to ensure against leaks, this oil filter endures a much higher burst strength than standard conventional filters.

Application. This Royal Purple Extended Life Oil Filter is specially designed for use on the 1994 to 2004 V6 model Mustang.

Read all positive reviews on various websites about this filter! Should be able to accommodate my once-a-year OCI with the Mustang. Thicker canister shell, silicone ADV, and glass media---a super deal for the price! Thanks,

I have been using royal purple filters and 5w30 royal purple oil and I find that my mustang performs better in starting and driving and seems to run cooler. I recommend to all mustang owners young and old great oil

First time using a Royal Purple product and I will be a lifetime user. It does everything product claims and more. There is a immediate noticeable change in my vehicle.I am purchasing Royal Purple oil at next oil change.

Back in the day, Royal Purple was known for additives and being the top in their field. Now, the same applies to their maintenance fluid. Cold starts are much easier on my Mustang and it runs like a mean machine from start to finish.

It's a great oil filter when paired with royal purple oil, I automatically noticed the difference when I ran my car with it. It just gives you the confidence that your car is running on a great quality oil with a great quality filter

this oil filter is the best oil filter on the market, i have used my fair share... but not one compares to royal purple, plus buying it from americanmuscle.com is way cheaper then the part store or any other website!!!

These filters are truly excellent, I talked to a Royal Purple representative on the phone to get all the filtration data for the filter before buying it and the high filtration efficiency at particle sizes of 15, 10, and 5 microns are a big selling point for this filter.
I have oil analyses preformed on my used motor oil and I found that with these filters I have been able to extend my filter change intervals significantly. I normally changed my filter at 4K and my oil at 8K with other premium filters, but with these filters I'm able to run one filter for the full 8,000miles when running Royal Purple motor oil.

Word on The Street

Once again another great product and service from American muscle. I have bought thousands of dollars from A.M and never had any problems and if I did they fixed it that same day. Shipping is the best that I have ever seen. Some times I get my product within 24 hours from placing the order. You can't beet that. That's why I will always do my mustang shopping at American muscle. Thank you.
